She has been a jury member at several piano competitions: Van Cliburn (US), Queen Elisabeth (Belgium), Montreal (Canada), Liszt (Weimar, Germany) and Busoni (Italy).

Her numerous recordings (more than 100 to date) for labels such as EMI, Decca, Atlantic, Finnadar and Naxos include the world-premiere recording of Liszt's transcriptions of the nine Beethovensymphonies (EMI 6LP/1986), complete solo piano works and concertos of Chopin (15CD/1992), of Brahms (12CD/1997), Rachmaninoff (10CD/2000) and the piano transcription of Stravinsky’s ballet music The Firebird (2003) and many others. Biret's wide repertoire encompasses much of the late Classical and Romantic piano literature. She is probably best known for her Chopin recordings[2], which won her the prestigious 'Grand Prix du Disque Frédéric Chopin' in Poland in 1995. In 2004 the sale of her Naxos CDs worldwide reached two million copies. Naxos commemorated this event by presenting Biret with a platinum disc. The same year the Boulez sonatas recording won the annual Golden Diapason award and was selected among the best recordings of the year by Le Monde newspaper in France.[citation needed]

Idil Biret has played in cycles the complete piano works of Beethoven and Brahms. In the 1980s she performed in two series of concerts Beethoven’s 32 sonatas and the piano transcription (Liszt) of all the 9 Symphonies, the latter broadcast live by Radio France. In the 1990s she played Beethoven’s five Piano Concertos, the Choral Fantasia and the Triple Concerto in five concerts. In 1997 she played all the solo piano works of Brahms in a series of five recitals in Germany during the composer’s centennial anniversary.

In September 2006 a biography "Idil Biret - Une Pianiste Turque en France" was written by a French author, Prof. Dominique Xardel and published by Buchet/Chastel in France. The book has been recently translated into Turkish and published by Can Yayinlari. The German translation of the book has been published by Staccato Verlag in September 2007. Russian translation will be available shortly. English translation of the book is also available in a special edition privately.

Recently, she recorded the complete Beethoven piano sonatas and concertos (including the Choral Fantasy) for her own label.[3] The results were released in 2008–2009 as an integral set, along with her 1986 EMI recordings of the nine Beethoven symphonies as transcribed for piano by Franz Liszt. The complete set will include 19 CDs. The first release is on December 16, 2008; the second will be in February 2009, with succeeding volumes released every other month. Biret recorded most of the sonatas near Brussels between 2001–2005 (three were recorded in 1994). She recorded the concertos with the Bilkent Symphony Orchestra conducted by Antoni Wit in 2008. Biret is the only pianist to have performed all of Beethoven's piano sonatas, concertos and Liszt transcriptions of the nine symphonies in public concerts. She is now the first pianist to have recorded them all.

Biret has been a State Artist since 1971, an honorary title issued to artists by the government of Turkey for their contributions into the Turkish culture.
